Hi,
I would like to know if there is any way to simply append to the next available row in an existing excel sheet. I know I can do the append with the writematrix function by specifying the 'Range' property.
writematrix(matrix_to_add, filename, 'Range', 'A1:D20'); %% this adds the matrix_to_add variable in the specified block
However, I do not wish to explicitly specify the range. The rows being added are quite long: 1000 elements. Hence, specifying range will be inconvenient. Thus, the solution I am looking for will simply add the row to the 51st row in the excel sheet if there are already 50 rows in the sheet.
Thanks!

If I recall correctly, with new enough versions of MATLAB, if you use writecell() then it will not change the format of existing cells.

This is how you can get it:
FName = 'DATA.xlsx';
for ii=1:5
writematrix(magic(3), FN, 'WriteMode','append')
end
